Abstract
Amateurs or hobbyists have made significant contributions to diatom research since the inception of our discipline in the late eighteenth century. Many of these contributions were made early in our history when there was little distinction between professionals and amateurs, and both could participate equally. But statistical methods and analytical tools used in diatom research have become increasingly sophisticated and expensive. Today, citizen scientists who have a passion for diatoms may feel excluded from research because they lack the requisite training, resources and connections. But even today, despite some obstacles, there remain many opportunities for the serious self-taught novice to make meaningful contributions to diatom science.
